All my 3900x's are now fully populated with 4 dimms. No issues.
Even if you had to drop to 3200, its no big deal from 3600. Now down to 2666 then it makes a difference.So the kit i mentioned above would work fine if i doubled down? I looked at the QVL list and for stand alone 32gb 3600mhz kits the timings are absolutely horrible. I would also save money just buying another 16gb kit of the same. I heard some boards require speed drops as low as 3200mhz but i can't recall the particular motherboards doing this.
Edit: would also need verification it works in Auros Master as this is the most likely replacement motherboard i have in mind. I assume since it may work in the Auros Elite then it should in the Master . I will be dumping the AE-5 as i forgot its a damper in any dual x8 dual gpu action plans. I will get some USB phones with 40-50mm drivers. Decided second gpu cause of crunching numbers for Folding@Home i will opt for the 2060 without a doubt.
My 88-thread computers take at the order of 10 minutes to start Rosetta on all threads. One can watch with e.g. "top" how the boinc client ist slowly starting one task after another. It is not possible to watch it with boincmgr, because boinc-client does not respond at the remote GUI port during this startup period.I have noticed on the dual Xeon (24 cores) machine I mentioned, that it does take a while to get all of the cores running sometimes.
Was the planned memory config of this 7742 a mixture of speeds, or/and sizes of DIMMs?Well, I got my memory today. The 32 gig 2933 would not post replacing the 2666 16 gig, so the 7742 is stuck at 110 gig.

Note that Rosetta is somewhat sensitive to memory overclocking. It may produce computation errors at memory settings at which more common workloads are still (appearing to) work OK.

But when I occasionally saw "waiting for memory" I looked for nemix 32 gig, and all I could find on the horrible amazon search was these 2933 32 gig. I tried them, and 5 2666 and 2 2933 just don't post. So its back to 110 gig and crunching away.My 88-thread computers take at the order of 10 minutes to start Rosetta on all threads.

Interesting idea. I just set this:PS,
what if you set <ncpus>5</ncpus> (or more) in cc_config/ options, in addition to the settings in post #209?
Linux? This could be legit reason to use zram, as a pretty good chunk of the rosetta files get shuffled into swap if you let it.Well, I was hoping 110 gig was enough, and quite often it is.

Yes, linux mint 19.2Linux? This could be legit reason to use zram, as a pretty good chunk of the rosetta files get shuffled into swap if you let it.
Well, I really went and messed up this config.Interesting idea. I just set this:
<options>
<ncpus>5</ncpus>
<alt_platform>aarch64-unknown-linux-gnu</alt_platform>
</options>
but it had not effect so far. this is a fire and forget Raspberry Pi - it will do nothing except crunch boinc.
Its not the end of the world, but its bugging me a little bit to have an idle CPU - it could be doing... something
You sure about that Tony? IIRC my Ryzen 3600 has an upper limit of 90C, would've thought that'd be family wide?But if you were not in eco mode, the stock cooler would be showing you 95C or so. That is hard to get used to, but it is well within spec.
That's for Rosetta, rather than BOINC overall .about how BOINC consumes about 1gb per task

Jeeper's bulletin #4:
"The Pentathlon is not only a question of processing power, but also of mental strength."
A 142 W CPU can be air-cooled very easily.
(Besides, as mentioned, it is quite unnecessary to have the PPT limit set as high as 142 W by default in the first place, in my definitely biased opinion.)
I currently have a ASUS rog x470 board with a 2700x in it. Apparently AMD is leaving it up to the MB makers to decide to support Zen 3/Ryzen 4000 in it. If I knew zen 3 would NOT be supported, I would buy a 3950x tomorrow. Unfortunately, it looks like I’ll have to wait for the announcement before I’ll get to find out what my mb will support.
